SewerCAD V8i uses the (Gradually Varied Flow) solver. While other software relies on simplistic Manning’s equation for uniform flow, the V8i exclusive solver handles:
SewerCAD V8i stands out by offering two distinct analysis methods within a single platform:
The exclusive combination of , TRex , GVF Convex solver , and ProjectWise integration created a workflow that was decades ahead of its competitors. Many senior engineers argue that no subsequent update has meaningfully improved upon the core stability and intuitive design of V8i.
Pricing for SewerCAD V8i was typically handled through authorized Bentley resellers like CSoft. Perpetual licenses were common, with maintenance through SELECT subscriptions providing access to updates and technical support. Contact Bentley Systems directly or authorized distributors for current pricing on OpenFlows SewerCAD, the modern successor to V8i. sewercad v8i exclusive
Rational method, time-area, and new ILSAX hydrograph methods 1.2.4.
Modeling future pipe expansions, realignments, or material changes.
While primarily a gravity flow tool, SewerCAD V8i handles (force mains) with ease. It uses the standard Manning’s equation for gravity pipes but seamlessly transitions to the Hazen-Williams or Darcy-Weisbach equations for pressure segments, allowing for a holistic view of the entire collection system. The User Interface: A Focus on Productivity SewerCAD V8i uses the (Gradually Varied Flow) solver
Integrated SewerCAD functionality into the Subsurface Utility Design and Analysis (SUDA) technology, enabling 3D physical modeling of sewer networks.
Run the hydraulic engine. Use the built-in color-coding tools to instantly highlight pipes that violate velocity or depth-to-diameter ( ) constraints.
LoadBuilder allows engineers to import data from GIS or CAD to allocate sanitary loads based on population, area, or water consumption data 1.2.3. Pricing for SewerCAD V8i was typically handled through
Its most powerful feature is the . Engineers are freed from tedious manual calculations. By setting specific boundary conditions (e.g., minimum pipe slopes, maximum velocities, or minimum cover requirements), the software automatically calculates optimal pipe diameters and slopes. It rigorously considers both existing and proposed infrastructure to minimize excavation volumes and material costs.
Simulates system behavior over a set time frame (typically 24 hours) to track flow patterns, storage utilization, and pump cycle behaviors. 2. Unified Gravity and Pressure Modeling
Bentley SewerCAD V8i is a powerful, highly specialized hydraulic modeling software designed for the design and analysis of sanitary sewer networks. While it has largely been superseded by Bentley’s CONNECT Edition, the V8i version remains a significant fixture in many engineering firms. It is celebrated for its calculation engine but often criticized for its user interface.
